Four parameters from Version 3 (menuVersion, isFrames, navFrLoc and mainFrName) are no longer used in Version 4. These four were true "global" parameters, and should only be applied site-wide. They have been moved to the new site-wide in-script Global Parameters, which we will be discussing in a future installment.

The parameter names have the HM_ prefix, to avoid conflict with other scripts. They also have an additional prefix (PG_) to easily identify them as page-specific. Finally, the descriptive part of their name is, in many cases, more descriptive than before, for easy purpose identification. For example, the confusing overCol has been changed to HM_PG_BGColorOver.

Six new parameters are introduced. These are HM_PG_ImageHorizSpace, HM_PG_ImageVertSpace, HM_PG_StatusDisplayBuild, HM_PG_StatusDisplayLink, HM_PG_UponDisplay and HM_PG_UponHide.
